Where Is The Debug Output??

[Alasdair]

OK... I know this is probably a silly question, but where does the output for "-debug" go to?

The output is dictated by the log.xml configuration file. By default it should go to stderr:

• -> convert -debug configure logo: null:
  2009-06-06T11:01:42-04:00 0:00 0.000u 6.5.3 Configure convert[20804]: configure.c/GetConfigureOptions/528/Configure
  Searching for configure file: "/usr/local/share/ImageMagick-6.5.3/config/coder.xml"

It does to stderr, which is good as it means it does not effect 'pipelines' of commands.

Get the calls to the image.c library module...
convert -debug trace present.c null: 2>&1 | grep image.c
